Thank you for purchasing an AKG product. This Manual contains important instructions for setting up and

operating your equipment. Please take a few minutes to read the instructions below carefully before

operating the equipment. Please keep the Manual for future reference. Have fun and impress your audience!

Check that the packaging contains all of the items listed above. Should anything be missing, please con-

tact your AKG dealer.

The CU 400 has been designed specifically for use with the WMS 400 system.

The charger provides two charging slots specially shaped to accept the HT 400/PT 400 transmitters. The

charging slots operate completely independently so you can charge two rechargeable batteries simulta-

neously. You do not need to remove the battery from the transmitter for charging.

Designed specifically for use with the WMS 400 transmitters, the CU 400 charger

• monitors battery voltages and temperatures during charging;

• generates a flag signaling the end of the charging cycle upon reaching maximum capacity;

• monitors all required safety parameters and will stop the charging cycle if one or more safety para-

meters are out of range.

The charger checks the battery inside the transmitter and will automatically deactivate the charging func-

tion if it detects a dry battery.

There is one STATUS LED in front of each charging slot.

These tricolor (red/orange/green) LEDs indicate the current operating status of the charger.

The DC 5V jack on the rear panel accepts the DC cable on the included AC adapter.

4.4 Important Notes

1. Check that the AC mains voltage stated on the included power supply is identical to the AC

mains voltage available where you will use your system. Using the power supply with a differ-

ent AC voltage may damage the unit.

Do not use any power supply other than the AC adapter supplied with the charger.

Never connect the CU 400 charger to the PSU 4000 central power supply because the output

voltage of the PSU 4000 is incompatible with the CU 400.

2. Connect the DC cable of the supplied AC adapter to the DC 5 V jack on the charger rear panel.

3. Connect the AC adapter to a convenient power outlet.

4. The charger is ready to operate. Note that both STATUS LEDs remain dark.

Rechargeable batteries (those included or those you may buy later) are delivered uncharged or

partially charged. Therefore, you will need to charge each new battery before using it.

Each charging slot features a tricolor STATUS LED that indicates the current operating status of the

respective charging slot (">…<" marks an LED flashing in the respective color):

1. Check that a rechargeable battery is inside the transmitter battery compartment.

Do not try to charge a dry battery.

If there is no battery inside the battery compartment, do not place the transmitter in a charging slot

before you inserted a rechargeable battery into the transmitter.

2. Make sure to switch the transmitter OFF before placing it in a charging slot.

This is the only way to guarantee optimum charging.

3. Insert the transmitter into the charging slot so that the display on the transmitter faces the LEDs on

the charger. The charger will automatically power the transmitter via the charging contacts.

4. Never switch the transmitter ON during the charging cycle. This may cause the charger to false-

ly indicate a completed charging cycle before charging is actually completed.

If the transmitter has been switched ON by accident during the charging cycle,

1. Remove the transmitter from the charger.

2. Switch the transmitter OFF.

3. Insert the transmitter into the charger.

The charging cycle will start automatically as soon as you insert a transmitter with a rechargeable battery

into the charger.

1. You may safely remove the transmitter at any time before the charging cycle is completed.

2. You may safely charge the battery inside the transmitter at any time, even before the battery is com-

pletely discharged.

3. At ambient temperatures above +40°C, the charger may overheat. As a result, the charging cycle may

take considerably longer or stop altogether (STATUS LED flashing red).

As soon as the ambient temperature drops below +40°C, the charging cycle will be resumed auto-

matically (STATUS LED will be lit red).

4. If the battery heats up to more than +60°C during a charging cycle (e.g., due to high ambient tem-

perature), the charging cycle will be stopped automatically (STATUS LED flashing red). Most batteries

will be unusable after being heated up to more than +60°C.

5. Excessive vibrations may cause the charging cycle to be stopped (STATUS LED flashing red), restart-

ed (STATUS LED is lit orange), or appear completed (STATUS LED lit green) ahead of time. Make sure

Important!

the charger will not be subjected to vibrations during the charging cycle and will rest firmly on a hard

surface.

6. Items 1 and 2 above notwithstanding, if you wish to extend the useful life of rechargeable batteries be

sure to

• completely discharge the battery every time, i.e., not to charge the battery before the battery warn-

ing appears on the transmitter display (see also the WMS 400 manual);

• charge the battery fully every time, i.e., not to remove it from the charger before the charging cycle

is completed;

• avoid charging batteries at temperatures below +5°C or above +40°C. At these temperatures, the

charging cycle will not start and the STATUS LED will be lit orange.

The charging cycle will be resumed automatically as soon as the battery temperature returns to the

acceptable range.

• use no batteries other than the rechargeable types recommended in section 7 Specifications.

7. Rechargeable batteries will only reach their full capacity after several charging cycles.

8. If you insert a transmitter with a dry battery into the charger, the charging cycle will be stopped imme-

diately after the battery test and a few minutes of charging. The STATUS LED will start flashing red.

Although there is virtually no risk of damaging the transmitter or charger, it is good practice not to

insert transmitters using dry batteries into the charger.

1. Disconnect the DC cable from the rear panel DC 5 V jack.

2. Use a cloth moistened (not wet!) with water to clean the surfaces of the charger.

Never use caustic or scouring cleaners or cleaning agents containing alcohol or solvents since

these may damage the enamel or plastic parts.
